Caseinophosphopeptides (CPPs) are a group of bioactive polypeptides hydrolyzed from caseins. Theaflavin-3,3'-digallate (TF-3) is a characteristic biofunctional polyphenol in black tea. In the present study, the interactions between CPPs and TF-3 were systematically investigated with fluorescence quenching, quartz crystal microbalance with dissipation monitoring (QCM-D), circular dichroism (CD), and small-angle X-ray scattering (SAXS). Both fluorescence quenching and QCM-D studies demonstrated that TF-3 interacted with CPPs primarily
